Fort MacArthur History
World War I
World War I began in August 1914 and the Panama Canal opened that same month. Construction began at Fort MacArthur 31 Oct 1914 and include the construction of three Taft Period Batteries (two 14" disappearing gun batteries and one 12" mortar battery). None of those batteries were completed before the end of World War I in 1918 but they were all completed and accepted in 1919.
The Fort MacArthur reservation was geographically divided into three parts: the Lower Reservation, Middle Reservation, and Upper Reservation. The Taft Period Batteries were located on the Upper Reservation. The lower reservation was a training center for troops heading to the war in Europe.

Post World War I
After the war Fort MacArthur returned to being a Coast Artillery post and became a training facility for the California National Guard. One additional gun battery (Lodor) was built in 1919 but decommissioned in 1927.
The Army installed one 14" Railway gun in 1925 and another in 1930 and additional anti-aircraft units were placed strategically around the larger gun emplacements. Because of public outcry over the test firing of the 14" railway guns they were transported to remote locations for additional firings and returned to Fort MacArthur for storage, ready for emplacement. Two special roundtable like emplacements that allowed the railway guns to traverse 360 degrees were constructed in 1937 at the ends of spur tracks on the lower reservation. Activity increased as World War II broke out in Europe and 1941 saw additional manpower and missions assigned to Fort MacArthur.

Current Status
In 1977 the Upper and Lower Reservations were deeded to the city of Los Angeles. All of the buildings on the Lower Reservation were removed and the property was dredged to create the Cabrillo Marina. The city of Los Angeles turned the Upper Reservation into a city park in 1982. In 1982 the Middle Reservation was transferred to the Air Force and used as a housing and administration facility for Los Angeles Air Force Base.
